Wow this is bad.
The spacing of everything is far too large such that navigating anywhere is a chore, involving several clicks and shifts and a lot of useless mouse work. That's a shambles. The coloring is juvenile, at best, and shows developers have run out of ideas. Still no easy way to print an email. After closing an email, do not take me to the next email without my consent. That is borderline aggression. What is full aggression, however, is putting ads in my face for everything I type.
You promised no ads, and these "suggestions" are big brother violation. In short, as always, your improvements are complete junk.
My account was just switched and agree!!!!! on the darned spacing issue! Now I see SO MUCH less on my screen then before. VERY VERY AGGRAVATING!!! Makes my email efforts LESS EFFICIENT. Microsoft, find a way to allow client to SWITCH the layout of compression of the screen in Beta. I DO NOT LIKE IT! One bit.
